Embodiment 1
[0024] The present invention is an environmentally friendly composite floor capable of absorbing formaldehyde, which is composed of multiple layers of wood veneers, and an adhesive layer is arranged between the wood veneers, wherein, the wood veneers are impregnated with a formaldehyde adsorption material dispersion, The formaldehyde adsorption material dispersion is prepared by the following method: 20 grams of ultrafine diatomite powder, 15 grams of ethylene urea, 5 grams of microcrystalline cellulose, 2 grams of sodium tripolyphosphate, and 48 grams of water are stirred evenly; Under dispersed conditions, continue to add ZnO / nano-TiO 2 10 grams of the composite material was ultrasonically dispersed for 2 hours and ball milled for 5 hours to obtain a dispersion of formaldehyde adsorbing material.
Embodiment 2
[0026] The present invention is an environmentally friendly composite floor capable of absorbing formaldehyde, which is composed of multiple layers of wood veneers, and an adhesive layer is arranged between the wood veneers, wherein, the wood veneers are impregnated with a formaldehyde adsorption material dispersion, The formaldehyde adsorption material dispersion is prepared by the following method: 10 grams of ultrafine diatomite powder, 20 grams of ethylene urea, 10 grams of microcrystalline cellulose, 1 gram of sodium tripolyphosphate, and 57 grams of water are stirred evenly; Under dispersed conditions, continue to add ZnO / nano-TiO 2 2 g of the composite material was ultrasonically dispersed for 1 hour and ball milled for 4 hours to obtain a dispersion of formaldehyde adsorbing material.
Embodiment 3
[0028] The present invention is an environmentally friendly composite floor capable of absorbing formaldehyde, which is composed of multiple layers of wood veneers, and an adhesive layer is arranged between the wood veneers, wherein, the wood veneers are impregnated with a formaldehyde adsorption material dispersion, The formaldehyde adsorption material dispersion is prepared by the following method: 30 grams of ultrafine diatomite powder, 5 grams of ethylene urea, 6 grams of microcrystalline cellulose, 3 grams of sodium tripolyphosphate, and 51 grams of water are stirred evenly; Under dispersed conditions, continue to add ZnO / nano-TiO 2 5 g of the composite material was ultrasonically dispersed for 3 hours and ball milled for 6 hours to obtain a dispersion of formaldehyde adsorbing material.
